I would go to timing then if u take the bolt from the top of the crankcase near the pull cord and use a timing light to look in the hole and see if the makes line up note if it is a two stroke u must have a two stroke timing light if it isn't right u have to remove the stator cover two change it also while your in there just go ahead and replace the key in the flywheel its only a dollar or two and could very well be the cause of your problem, hope this helps...

I would check the air filter. It might be very clogged and need a cleaning or replacement.

Polaris ranger 800 was running then just killed won't starts spins over


Hey Timothy,
First, make sure the kill switch is not on "kill"
An internal combustion engine needs three things to run:
1. A properly timed spark - 2. delivery of a proper air/fuel ratio - 3. adequate compression >120PSI. (make sure air filter is clean and treated)
NOW -
1. Install a new, correct, spark plug. - MAKE SURE it firing.
2. Make sure you are getting fuel to the carburetor.
3. Make sure you are getting fuel THROUGH the carburetor.
4. Make sure you have compression. 120psi+

One (or more) of these 3 requirements is NOT happening.. eliminate one at a time!!

2007 Polaris phoenix 200, has new fuel cleaned carb,good blue spark,fires don't start or run,plug lil wet but not flooded or soaked


If you have spark at the right time, fuel, air.... you might try a spray of staring fluid. I would then check the compression. If it is too low it will not start.

I have a 2016 Polaris sportsman 570 she's got a fuel pump tries starting her she will keep winding over but won't start any help would be nice


Make sure the kill switch is in the run position.

AN engine need three things to run:
Compression
Timed spark
Fuel

now.....
1*. Check the spark plug to make sure it is firing.. remove the spark plug.. make sure you have metal to metal contact and then turn the engine over.. (this might be a two man job).. the spark plug should have a nice big blue white spark,,(some electronic's will have a weak orange and still fire fine!)
2. Make sure you have gas in the tank and (going into the carb/FI)... (have to ask-actually have had 3 bikes in my career come in complaining -won't start...!! Add gas and they ran.. WOW!.. never charged any of them....the embarrassment on their face was payment enough!)
3*. While the spark plug is out... place your finger over the spark plug hole firmly .. keep the spark plug cap away from your hand..turn the engine over and see if it will blow your finger off..(it should blow it off the hole easily).

If any one of these three are not nearly perfect.. you have an issue!!

Check these and repost with the results...

Has good compression,getting fuel,plenty of spark, wont start


Then either the fuel is bad or it's flooded. Dry the plug, crank it without the plug to fry the cylinder & start with starter fluid to replace fuel. If it starts. Clean & blow out the entire fuel system, lines, pump,carb. Good luck.

2006 arctic cat wont start


If you've got decent compression, spark and fuel and it wont run - what about about air? Clean / new air filter installed? All 4 are needed to run.

Why cant anyone answer questions about this hawkeye atv


Have you checked the Spark Plug ? No Spark & No Fuel means not going to start and run. If you are getting fuel then your Spark plug may need to be cleaned or replaced or even re-gaped. Spark plugs have a tendency to get fouled out. Meaning oil gets on it and it can not throw a good spark. If you do have a good spark then check the choke and or the float in the carb.

Thanks for allowing my in-put!

Whhy doent my sortsman want to start ??


ok 4 things could be the problem,
check to see if you have spark. if you have spark then spray some starting fluid into the carburetor or air box. if it does not start then check the compression, if the compression is good, and you have spark then check the camshaft. these have been known to eat the exhaust lobe of the camshaft right off. that is where i would start.

1996 Polaris Sportsman 400 Will Not Start


If your atv has been sitting this long, the carb is probably stopped up internally... take the carb to a qualified professional and have it cleaned and set...(take a few pictures so you know where all the hoses re-attach)

ALL it takes for an engine to run is:
1. A timed spark
2. Adequate compression
3. Proper fuel/air ratio delivered
